They are a little bit unstable. I had Code Dumps too with these...
Use Configurable USB Loader. It´s a stable loader. Read the "config-readme.txt". You can adjust, that the loader starts in GUI Mode (Video at Topic) so you have a stable and nice looking loader.

Configurable Loader is by far the most stable one in my experience. Worked exactly as advertised whenever I used it. The only thing that has ever given me issues is the BlueMatrix-themed Forwarded Channel for it.

I get the most code dumps with GX, but the UI is too pretty to pass up. I might run out of patience any time, though.
